protools mbox noise

[jmorris]

I have an mbox2 factory. Issue is there is a wicked noise when connecting to monitors via 1/4' output (trs). Oddly it is fine with headphones from headphone jack. But, if I go out from headphone jack with single stereo trs to dual mono trs to monitors, same noise. Anyclues? Audio runs fine.

Here are some things you can try:
*Connect the headphones to the trs outputs. If there's no noise, then it might rule out the mbox2 as the source of noise.

*Try the monitors with a different sound card.

*Try the RightMark Audio Analyser test.

I also have sonar on this laptop and mackie onyx drivers for my remote 16 channel mackie onyx mixer along with drivers for motu 2408 that I use with sonar.. Conflics? I have a lot of experience with sonar but this is my first time with protools. I bought the mbox to be able to have a very light and portable recording setup for doing video and 2 track(stereo) of audio then sync them together.
